/**
 * DIAMOND MODAL MODERNIZATION - PHASE 1, 2 & 3
 * =============================================
 *
 * Phase 1: Responsive Modal Overlay System
 * - Mobile (< 768px): Full-screen overlay
 * - Tablet (768-1439px): Bottom-sheet (60% height)
 * - Desktop (1440px+): Side panel (35% width)
 *
 * Phase 2: Tab System with Media Priority
 * - Actual Image first (loads immediately)
 * - 360° Video secondary (preloads in background)
 * - Certificate view (tertiary)
 * - Sample image fallback
 *
 * Phase 3: Design System Alignment (2025-01-10)
 * - Typography: Match B2C Jewels design system (28px titles, #0088cc prices)
 * - Colors: Exact hex matches from detail page analysis
 * - Borders: 4px buttons, 3px form fields
 * - Spacing: 4px grid alignment
 * - Shadows: Softened, brand-blue focus states
 * - Transitions: 200ms standard

/* ============================================================================
   360° VIDEO FORM COMPACT DESIGN - FIT WITHOUT SCROLLING
   Date: 2025-11-11

   PROBLEM: Form height (~427px) exceeds modal tab container heights:
   - Mobile: 350px container
   - Tablet: 380px container
   - Desktop: 400px container

   SOLUTION: Reduce form element sizes/spacing to fit in ~323px:
   - Icon: 80px → 60px
   - Heading: 22px → 18px
   - Description: 14px → 13px (tighter line-height)
   - Padding: 24px → 16px
   - Field spacing: 8px → 4px
   - Labels: 14px → 13px
   - Inputs: 8px padding → 6px padding
   - Textarea: default → 60px min-height
   - Button: 12px padding → 10px padding
   - Privacy note: 12px → 11px

   RESULT: Form fits completely in all containers WITHOUT scrolling:
   - Mobile 350px: ✅ (323px form + 27px margin)
   - Tablet 380px: ✅ (323px form + 57px margin)
   - Desktop 400px: ✅ (323px form + 77px margin)
